Extraction of the higher risk of neurogenic UUTD established in this study indicated two classification rules, one is normal urethra function, Pabd max > 14 cm [H.
The evaluation indices for the risk of UUTD using the decision tree are illustrated in Table 3.
001), showing a good fitness between the prediction results and the actual morbidity of UUTD.
UUTD in NGB includes a series of complications such as pyeloureterectasis, hydronephrosis, VUR and renal insufficiency (13).
The present study established a decision tree model to excavate the major risk factors for UUTD in NGB patients.
9% of patients with UUTD showing normal urethra function, while none of the patients showing incompetent urethra function was with UUTD.
In our study, Pabd max and Pves max were valuable predictive variables for risk of UUTD in NGB patients.
The present study showed that gender is also a predictive variable for risk of UUTD in NGB patients.
The decision tree model for risk of neurogenic UUTD established in this study summarized two classification rules.
